MACHINERY FOR BURNISEHIN'G THE sore-totes 0F BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 255,152, dated March 21, 1882.

' Application filed November 14, 1881. (No model.)

To all whom it may concern:

Be it known that I, MYRICK DUDLEY, of Lynn, of the county of Essex and State ot'Massachusetts, have invented a new and useful {Improvement in Machinery for Finishing or Burnishing the Edges of the Fore Parts and Shanks of Shoes; and I do herebydeclare the same to be described in the following specification and represented in the accompanying 1o drawings, of which- Figure 1 is a top View, Fig. 2 a front elevation, Figs. 3 and 4 end views, of a machine embodying my invention, the nature of which is hereinafter explained, and particularly set forth, especially in the claims as presented.

Fig. 5 is hereinafter explained.

In such drawings, A denotes a sole-edge finisher or burnisher, which may be supposed to be substantially like that described in Letters Patent No.246,944, granted Septemberl3, 1881, on an invention made by me. Such finisher is connected with a carrier, 13, so as to slide up and down on and relatively thereto, such adaptation being by means of a dovetailed J5 tongue, a, projecting from the one into adovetailed groove, 1), in the other, as shown in Fig. 5, which is a transverse section of the finisher and its carrier. A spring, (J, fixed to the car.- rier and arranged therewith, as shown, bears 0 on the upper part of the finisher, and thus affords an elastic support for the said finisher. The carrier projects into and is pivoted to a forked arm, D, which has in one of its prongs a set-screw, c,which, arranged as represented,

with the joint-pin d of the carrier and arm, serves to clamp the carrier to the arm. By means of the carrier applied, as described, to the arm the inclination of the fore part or edge finisher can be varied more or less in the 40 plane of the carrier. From the upper part of the said finisher a'tenon, 6, projects through a mortise in a shank burnishcr or finisher, E, arranged with the finisher A, as represented, and held thereto by a set-screw, f, screwed into 5 the said finisher E and against the said tenon. The forked arm D, at its rear part, is jointed to a rocker-shaft, F, supported by a frame, G.

, From the forked arm a curved bar, g, extends pin, 1, which should be adjustable radially in the said slot.

On a driving-shaft, m, arranged, as shown, in the frame G, there is fixed a pulley, 0, provided with a diametric slot, p, having to it a crank-pin, q, adjustable radially in the slot.

A connecting-rod, '2', turns on the said two crank-pins. The two shafts F and m are supported in hearings in the frame G.

H is a finger-rest, adapted to swivel transversely of it in an ear, I, projecting from a radial arm, K. This arm K, pivoted at its rear part to the frame G, has a curved and slotted bar, L, extending upward from it. A clampscrew, M, goes through the slot 8 of the bar L and screws into the frame G, from which a tenon, t, projects into or through a mortisein a stand, N. A set-screw), screwed into the .stand and against the tenon, serves to confine the tenon at any altitude in the stand.

By having thecrank-pins l and q adjustable nearer to or farther from the axes ofthe shafts F and m I can vary the extent of the reciprocating motion of the rocker-shaft, and consequently that of the edge-finisher, at any inclination of the arm D to the shaft F. Each of the crank-pins land q is to be supposed to be provided with means of clam ping it in any position in which it may be adjusted in its sustaining-slot.

As a shoe while being operated on by either of the finishers is to be supported by a jack, it will be seen from what has been hereinbefore explained that I have means of not only adjusting either finisher into its due relation to the shoe, but of imparting a vibratory motion to such finisher and regulating the extent of 55 such vibration, as circumstances may require;

and, besides, I have means of adjusting the 3. The combination of the connecting-rod r finger-rest in a vertical plane and of turning and the driving-pulley 0 and disk 1', provided it laterally, in order to bring it into a convenwith crank-pins l and q, adjustable in them, as

ient position relatively to the shoe. set forth, with the shafts m E and with the 20 5 What I claim as my invention is as follows, finisher-carrier supporting-arm D. applied to viz: the rocker-shaft F, so as to be adjustable 1.
